Pivot Bearing Specifications

These are the core bearings for your suspension linkage.

Main Pivot (BB Area) 2 15 × 28 × 7 mm 6902 Enduro MAX 6902 LLU MAX

Hardware: Bolts & Washers

Keep these organized during teardown; the head sizes are identical, but the lengths vary significantly.

Pivot Bolts

  • 2x M8 x 31 mm (with 2.5 x 18.5 head)
  • 2x M8 x 20 mm (with 2.5 x 18.5 head)
  • 2x M10 x 16 mm (with 2.5 x 18.5 head)

Washers / Spacers

  • 6x 15 x 2.3 x 8 mm (Internal)
  • 2x 14.2 x 2.5 x 10 mm (Internal)

Headset Bearings

Standard 52mm (1.5") outer diameter for integrated or internal headsets.

  • Upper: 52 x 40 x 6.5 mm
  • Lower: 52 x 40 x 7 mm

Pro Tip: Since these are pivot bearings, stick with the MAX (Full Complement) versions you've listed. They lack a retainer, allowing for more balls and a higher load capacity, which is exactly what high-pressure, low-rotation suspension pivots need.
